Definitions

  • the invention relates to a hub, especially for clutch disks of motor vehicles and, more particularly, to such a hub wherein a flange alone or a flange with at least one additional part extending in radial direction is fastened on a cylindrical hub body and at least one of the parts, hub body and/or flange have been provided with a profiling in the form, for example, of a toothing, to achieve a form lock effective at least in circumferential direction and, for securing the pushed-on part or parts in both axial directions, abutments, of which at least one is formed by wedging-over, are formed at the hub body on both sides of the part or parts.
  • a clutch disk of this general type with a toothing is pressed onto a shoulder part of the hub body until the flange makes contact with an abutment extending in radial direction, which secures the flange against further displacement in one axial direction.
  • a washer is provided on the side of the flange facing away from this abutment and, to secure the flange in the other axial direction, a wedged-over joint is formed against this washer from portions of the hub body wedged in direction toward the washer.
  • Such a hub can be made, however, without a washer also, the wedging-over portion resting directly against the flange.
  • a hub comprising a cylindrical hub body and means comprising a flange member for flanging the hub body, the flanging means being slidably mounted on and fastened to the hub body and extending in radial direction, at least one of the hub body and the flanging means being formed with profiling for effecting a form lock against relative movement thereof at least in circumferential direction, a respective abutment formed on the hub body on each side of the flanging means, at least one of the abutments being a wedged-over portion of the hub body received in a channel formed in the flanging means.
  • the wedged-over portion is received, for example, in a channel that had previously been formed in the flanging means by stamping.
  • the parts that are to be inserted between the flange and the friction lining support and/or a counterdisk, or the lining support of the counterdisk or the counterdisk per se come to lie on the wedged-over portion that is formed, and are thus not installed concentrically or coaxially and properly with respect to the hub body.
  • an advantage is derived therefrom of obtaining an enlargement of the friction surface by the additional availability of the area occupied by the radial zone wherein the wedged-over portion is received, at least when, in accordance with a further embodiment of the invention, the wedged-over portion merges flush with the surface region which is adjacent in radial direction. A reduction of the surface pressure thus occurs, and the thickness of the friction or sliding ring can be reduced.
  • the flanging means include at least one other part besides the flange member, the part extending in radial direction and being formed with the formlocking profiling.
  • the flanging means include at least one other part besides the flange member, the channel being formed in the other part.
  • the flange member extends in radial direction and is formed with the formlocking profiling.
  • the channel is formed in the flange member.
  • the channel is formed in a radially extending surface region of the flanging means, and the wedged-over portion of the hub body received in the channel is flush with the surface region.
  • FIGURE of the drawing is a half-sectional view of a clutch disk incorporating the hub of the invention.
  • FIG. 1 there is shown therein a friction lining support disk 1 connected in a conventional manner to a counterdisk 2, so that it is secured against rotation relative thereto.
  • the disks 1 and 2 encloses therebetween, a flange 3 of a hub 4 and are rotatable relative to the hub 4 against biasing action of coil springs 5.
  • the hub 4 is formed of a hub body 6, onto which the aforementioned flange 3 is slid or pushed in axial direction in a conventional manner, and is then wedged or pressed or crimped over.
  • the flange 3 has a toothing or serration 7' (only one of the teeth thereof being shown in the FIGURE) with which the flange 3 is slid or pushed onto a shoulder 7 of the hub body until it makes contact with an abutment 8 which is formed on the hub body 6 and which extends in radial direction.
  • the flange 3 is secured in the other axial direction by a wedged-over portion 9, which is pressed into a channel 10 formed in the flange 3 in the embodiment of the FIGURE and which merges flush into the surface zone 11 of the flange 3, next adjacent thereto in radial direction.
  • Friction or sliding rings 12 and 13 are provided on both sides of the flange 3.
  • An intermediate disk or washer 14 engages the friction or sliding ring 13 and a cup or plate spring 15 is disposed between the intermediate washer 14 and the counterdisk 2.
